OSCAR M. LACKIE, OF DULUTH, MINNESOTA.

SNOWPL W.

Application filed March 30, 1923. Serial No. 628,690.

To all whom it may concern:

Be it known that I, Osonn M. LACKIE, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Snowplows, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain improvements in snow plows and has special reference to a V-type of such a plow of such construction as to clear a road of deep snow with the least power possible.

Another object is to provide the plow with means for lifting the snow from the travelled portion of the road onto the banks at the sides thereof.

Further objects and advantages of the construction will appear in the further description of the invention.

Referring now to the accompanying drawing forming part. of this application;

Figure 1 is a top plan view of my improved plow;

Figure 2 is a. front elevation of the same;

Figure 3 is a side elevation; and

Figure 4 is a perspective view of a modified form of plow.

1 represents the usual V-type of snow plow, the sides of which are braced by the heavy channel iron 2, which are in turn supported by the batten braces- 8 and tongue 4. To the rear side of the channel 2 is se-- cured in any desired manner a pan of chan-' nel clips 5, to which the connecting beams of the tractor, or other power means, are attached. The bottoms of the sides of the plow are flared outwardly as at 6, as is common to such devices.

To the sides of the plow and a short distance from the nose thereof there are attached in any desired manner, as by the batten braces 7, the inclined elevator wings 8 which decrease in width toward the upper or rear end thereof, and, if preferred to ward the upper end they may be made to tip downwardly slightly to assist in forcing the snow from the upper end thereof.

Thus in operation when the plow is forced into the snow, the nose of the plow will break up the snow and start forcing it diagonally to the side of the road, when the wings 8 will elevate it so that when it does eventually fall from the upper rear end of the wings it will fall on the top of the banks at the roadside.

I have shown in the modified form in Figure 4, a nose piece 9 which may be secured to the apex of the plow, and which nose piece 9 is arouately shaped so that in the event of the plow striking a large stone or stump the nose piece will raise the entire plow over the obstruction.

It also may be found desirable for the lower end of the wings to be on a line with the, apex of the plow as shown in Figure 4 to produce the best results, and other obvious modifications of construction may be resorted to without departing from the spirit of the invention as pointed out in the following claim.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is.

The combination with a plow of the character described having a convex arcuately shaped prow, of straight fiat inclined lifting wings, the forward ends of which terminate so considerably back of the forward end of the plow.

In testimony whereof I hereunto aiiix my signature.

OSCAR M. LACKIE.
